Abstract: 294,524. National Acme Co., (Assignees of Paterson, D. S., and Petsche, G. B.). July 25, 1927, [Convention date]. Density separators; casings; driving.-A rotary separator for liquids has a bowl with a series of annular compartments through which liquid travels in opposite directions, and ported discs at the upper and lower ends of the bowl. The bowl 4 is mounted within the casing 2 and is driven by the motor 10 by means of a belt 18 which passes over guide pulleys 19, 20 to the pulley 21 on the shaft 22. The motor is mounted on an adjustable platform 9 and the driving pulley 13 may be changed for another of different diameter to vary the running speed of the bowl. A brake lever 27 can be operated by an external handle to bear upwardly on the brake shoe 29 which acts on the bottom plate 7 of the bowl. The movement of the brake lever is limited by. the engagement of the lug 30 with the casing. The bowl 4 contains an imperforate cylinder 48 and a cylindrical filter 52, while a tubular member 53 runs from the bottom of the bowl through the top plate to enclose the inlet 54 which is controlled by the valve 56. Radial passages 50 in the bottom plate 49 communicate between the tubular member 53 and the bowl 4 The mixed fluids, for example oil and water, to be separated and clarified, pass through the inlet 54 and passages 50 to the compartment 69 of the bowl. The heavier liquid, the water, rises up the wall of the bowl 'and passes through the openings 72 in the upper disc 51 and is discharged from the opening 74 into the chamber 40 with the nozzle 43. The lighter liquid, the oil, rises up the outside of the wall 48 and then passes inwards through the opening 70 into the compartment 71. It is then strained or filtered through the screen 52 and rises until it is discharged through the opening 77 into the chamber 41 with the nozzle 44. Openings 68 are provided in the wall 48 so that any water in the compartment 71 may pass back into the bowl 4. Any excess fluid supplied escapes into the chamber 42. Within the collar 60 is a sliding collar 66 with a spring 67 to take up play and vibration. A door 79 in the lower part of the casing permits access to the spindle and its adjuncts. A lever 31 on a pivot 32 has a cam 33 which coacts with the end 34 of a lever the other end 36 of which is bifurcated and engages in openings in the bottom plate 7 of the bowl. When it is desired to clean the bowl or to interchange any of its vessels, the cover 39 containing the discharge chambers is removed and the lever 31 is operated. This causes the bifurcated end 36 of the other lever to lift the bowl 4 from its engagement with the head 25 of the spindle 22. The door 5 of the casing can then be swung open with the bowl resting on the bifurcated end 36 of the lever and secured to the inside of the door by the ring 38. A ring acting as a weir may be inserted in the passage 73 leading to the discharge opening 74; the ring selected is of a size to reduce the channel to an appropriate size for the liquid under treatment.

Title: Method of measuring the bit error rate of a regenerated pcm transmission path
IPC: H04L1/00
Filed: 1975-04-07
Abstract: 1492134 Data transmission; channel testing WANDEL & GOLTERMANN 7 April 1975 [23 April 1974] 14172/75 Heading H4P An arrangement for measuring bit error rate of a regenerated bipolar system comprises transmitting a test quasi random pattern which is compared on reception with a similar locally produced pattern synchronized by clock extraction from received bits and adjustable delay of local pattern. Synchronization disturbance, pattern error, and single bit and pair errors are detected separately. In a bipolar system comprising a coder 15, line terminations 8, 11, regenerators 10 and decoder 13, test signals generated by a quasi random generator 1 from one of several test words, passed through adjustable coder 3 having by pass switch 6, are injected at 7 (or 16) and tested for fidelity at 12 (or 16<SP>1</SP>-). Opposite polarity limiter amplifiers 17, 18 both provide positive outputs through adjustable decoder 42 and by pass switch 40,40<SP>1</SP> to lines 19,20. The local pattern is generated from similar test words at 23 through coder 25 also having by pass switch 44, and fed through poled limiter amplifiers 27, 28. Coder 25, if set to bipolar conditions, has flip-flops storing coding conditions dependent upon polarity of final bits, and possibly coding conditions depending on final bit mutilation of applied pattern. A clock extraction circuit 29 via AND 30 controls local clock generator 23. Bit error detector 31 receiving signals on lines 19-22 detects individual errors also inserted or omitted positive/negative bits and in combination with a polarity detector 32 provides outputs to 25 which reverses coding conditions. A comparator 37 provides, per bit, error signals direct to the forward counting terminal of counter 39 and correct signals through 1/m divider 38 to the backwards terminal. Output of 39 initiates pattern synchronization at error rates equal to or greater than 1/m to gate 36; this also receives output from a polarity independent comparator 34 hence primes gate 30. If test signals are injected at 16 and tested at 16<SP>1</SP>, by pass switches 6 and 44 will be placed in the reversed position.
